How do I install the Clangd Lsp skill?

Run npx skillmds@latest add johnalbertini14-glitch/clangd-lsp in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Clangd Lsp safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. Capability flags: makes network calls. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Clangd Lsp?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Clangd Lsp free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

Clangd Lsp

C/C++ language server (clangd) providing code intelligence, diagnostics, and formatting for .c, .h, .cpp, .cc, .cxx, .hpp, .hxx files. Use when working with C or C++ code that needs autocomplete, go-to-definition, find references, error detection, or refactoring support.

File contents

clangd LSP

C/C++ language server integration providing comprehensive code intelligence through clangd (part of LLVM).

Capabilities

Code intelligence: Autocomplete, go-to-definition, find references
Error detection: Real-time diagnostics for compilation errors
Formatting: Code formatting with clang-format
Refactoring: Rename symbols, extract function
Supported extensions: .c, .h, .cpp, .cc, .cxx, .hpp, .hxx, .C, .H

Installation

Via Homebrew (macOS)

brew install llvm
# Add to PATH
export PATH="/opt/homebrew/opt/llvm/bin:$PATH"

Via package manager (Linux)

# Ubuntu/Debian
sudo apt install clangd

# Fedora
sudo dnf install clang-tools-extra

# Arch Linux
sudo pacman -S clang

Windows

winget install LLVM.LLVM

Or download from LLVM releases.

Verify installation:

clangd --version

Usage

The language server runs automatically in LSP-compatible editors. For manual operations:

Compile

gcc file.c -o output      # C
g++ file.cpp -o output    # C++
clang file.c -o output    # with clang

Format code

clang-format -i file.cpp

Static analysis

clang-tidy file.cpp -- -std=c++17

Configuration

Create .clangd in project root:

CompileFlags:
  Add: [-std=c++17, -Wall, -Wextra]
  Remove: [-W*]
Diagnostics:
  UnusedIncludes: Strict
  MissingIncludes: Strict

Or compile_commands.json for complex projects:

cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON .
# or
bear -- make

Integration Pattern

When editing C/C++ code:

clangd uses compile_commands.json for project understanding
Run clang-format to format code
Use clang-tidy for static analysis
Compile with warnings enabled (-Wall -Wextra)

Common Flags

Compile flags:

-std=c++17 - C++17 standard
-Wall -Wextra - Enable warnings
-O2 - Optimization level
-g - Debug symbols
-I<path> - Include path
-L<path> - Library path

clang-tidy checks:

clang-tidy file.cpp --checks='*' --
clang-tidy file.cpp --fix --  # Auto-fix
